It is not that your laptop does not support CPU power management. I'm sure, given what you've said, that it does. However, there is no support in Solaris for CPU power management of your laptop. The Solaris CPU driver that provides CPU power management support, fails to support your processor family/model. I can only imagine that something in the BIOS is causing this behavior on suspend/resume. You might want to check your BIOS settings.
